CVEN1300 Engineering Mechanics

Hand-in Tutorial

Total number of Questions: 10

Submission Date:This tutorial is to be submitted to the assignment box labelled “GAO” on 6th Floor in CEBuilding (next to the computer lab) by 5.00pm on Friday 16 September 2011, Week 8. Latesubmissions will not be accepted.

Plagiarism:Beware. Plagiarism will not be tolerated! Identical submissions (and these are so easy totrack!!) will be marked zero regardless of who copied from whom.

Group work:I encourage you to work with your peers, although this is to be submitted as an individualwork. A good way to learn the material is in small study groups. Such groups work best ifmembers have attempted the problems individually before meeting as a group. A valued andhonest collaboration occurs when, for example, you “get stuck” early on in attacking anexercise and go to your classmate with a relevant question. Your classmate then has theopportunity to learn from your question as well as help you. You then bring something to thecollaboration. If someone offers you to copy their work, please keep on mind, they are takingaway from you an opportunity to develop important engineering skills (and both of you willscore zero!!).

Presentation: All your workings must show detailed calculations. Presentation and neatness will alsocontribute towards your tutorial mark.

Question 1: (2009 Quiz)

For the simply supported beam shown in Figure 1,1) Calculate the reactions at B and E.

2) Draw the shear force and bending moment diagrams, clearly indicating the magnitude and sign of all

actions at A, B, C, D and E.

Question 2: (2009 Exam)

The simply supported beam shown in Figure 2 carries a uniformly distributed load and two concentratedloads as shown.

1) Calculate the reactions at A and C and draw the shear force and bending moment diagrams,

clearly indicating the magnitude and sign of all actions at A, B, C and D.2) Determine the position and magnitude of the maximum positive moment.
